This study used econometric panel models to examine the influence of water shortage on economic growth in Central Asian countries. To evaluate long-term panel data, we used a pooled regression model, a fixed effect model, and a random effect model on annual data from 1990 to 2023 across five nations. After creating the models, we ran diagnostic tests using several statistical techniques. After analyzing the models listed above, we determined that the Pooled regression model is best suited to our panel data. Based on the indicators of this model, it was discovered that increased water shortage in Central Asian countries had a negative impact on economic growth. Each unit increase in water scarcity causes a 0.0166 unit loss in GDP. The findings suggest that countries experiencing severe water scarcity should prioritize water resource management and establish a water conservation program that includes the construction of infrastructure to alleviate the shortage.

This article presents a comprehensive analysis of student mobility and tourism flows in Central Asia, drawing on the experience of the European Union. The economic impact of student flows is assessed through empirical analysis, which confirms the long‑term economic efficiency of the “student‑tourist” synergy.

Knowledge of optimal monetary policy and frequently the rules of optimization in flexible inflation targeting assign central banks the task of developing all types of cyclical policies. The goal of optimal inflation policy is to achieve macroeconomic stability and stimulate sustainable economic growth. To determine the amount of monetary policy associated with the rule of monetary policy and to establish the proposed optimal inflation target, we use the DSGE econometric model. The relationship between r (refinancing rate) and the optimal inflation target has a downward slope. Although the growth of the optimal inflation level is smaller than the decrease in r, it has been found that in areas with current empirical significance, the slope of the relationship is close to -1. This angle parameter is sufficient to ensure uncertainty. It was found that in strategies such as price level setting and their diversity, the optimal inflation target is significantly lower and less sensitive to r."*

Purpose: This study aims to investigate the intricate relationship between the volume of exports (Y) and freight turnover on railways (X) through a paired linear regression model. The purpose is to discern the quantitative impact of railway freight turnover on a nation's export volumes and offer insights for policymakers and stakeholders in the transportation and trade sectors. Design/Methodology/Approach: A quantitative research design is employed, utilizing historical data spanning from 2000 to 2022. The chosen methodology involves the estimation of a paired linear regression model using the method of least squares. Statistical significance is tested through the coefficient of determination, Fisher's F-test, and an examination of heteroskedasticity. Elasticity analysis, rank correlation, and graphical assessments of residuals provide a comprehensive understanding of the relationship. Findings: The research reveals a strong and statistically significant positive correlation (r = 0.92) between export volumes and railway freight turnover. The regression model, validated through multiple tests, explains 84.72% of the variability in export volumes. Economic interpretation indicates that a one-unit increase in railway freight turnover leads to a substantial average increase of 1627720.728 units in export volumes. The absence of heteroskedasticity reinforces the robustness of the model.

Over the past decade, digital distance learning platforms have become a key element of the global education services market, which reached approximately USD 369.7 billion in 2024 and is projected to exceed USD 731.8 billion by 2034. The article proposes an analytical model for assessing the economic effectiveness of distance learning platforms, taking into account three groups of indicators: costs (licensing, infrastructure, content, and support); student engagement (user activity, time on platform, course completion rate); and the quality of educational services (satisfaction, academic performance, career outcomes). A comparative economic analysis is conducted based on data from Coursera, edX, Udemy, LinkedIn Learning, and Khan Academy for 2023–2024. It is shown that the introduction of digital platforms enables educational institutions to reduce operating costs by 20–35% while simultaneously increasing the accessibility of education. The findings are applicable for managing the quality and financial sustainability of educational programs in the Republic of Uzbekistan.
